I think that being able to move with the "wasd" buttons would make this game a lot easier to play. w=north, =a=west, s=south, d=east. (using the diagonal north, just like it is on the mini map).
Positive: It would allow for clicking on objects and moving to work together better.
Negative: It would be easier for players to create macros simpler.
Other possible solution: make path finding apply to hearthlings, similar to when you use milestones.
